sc1aims. (ci. 15-16) Y Y The present invention relates to suctioncleaners and more particularly to a new and novel suction cleaner casingconstruction.

An object of the invention is'to provide a new and improved suctioncleaner. Another object is to provide a built-up cleaner casing ofstamped metal parts which are of improved design and permit economy ofmanufacture and assembly.

' Further objects and advantages of the invention will be apparentfrom'the following description and the attached drawings, wherein:

The embodiment of the invention herein disclosed comprises a suctioncleaner having a body or casing III formed from a plurality `of metalstampings identified generally as a shell II, fan casing section I2,base I3 and brush roll housing I4. The base I3 is formed from a metalblank stamped to provide a nozzle I5 having a front wall I6, oppositeend walls II, AI1 and a top wall I6, the latter being provided with anupwardly extending arcuate wall I6 to define with the front wall I6extends rearwardly from the nozzle I5 to the rear end of the cleaner toforml spaced' aprons 2|, 2Ibetween which'is a depressed wall 22 deiininga recess 23 for a motor, the aprons 2|, 2l and depressed wall 22 mergingat the rear end of the base and terminating in a depending skirt 24which extends from the rear of the cleaner body along both sides of thelatter to the nozzle end walls I1, I1.. An opening 25 is providedbetween the depressed wall 22 and the arcuate wall I3 for theaccommodation of the' fan casing section I2.

A brush roll housing I4 is also formed from a metal blank stamped toprovide a front 'wall 33, top wall 34, end walls 3l, 35 and a rear wall36, such walls lying adjacent the nozzle walls of the base I3. An openim3l is formed in the top wall 34 by a neck section 33 which extends aslight distance into the arcuate wall I3 and contacts the inner surfacesof -the latter and the iront wall I6 to form an air-tight sealtherebetween and thus provide a suction air passage- Way 33. The housingI4 and base I3 may be spot welded together at available places and amarginal flange 40 at the nozzle mouth is bent over a cooperatingmarginal flange 4I on the base I3. The front and rear nozzle lips 42 and43 on the suction` nozzle mouth are formed by a stamped metal frameremovably mounted on the housing I4 by means of a marginal flange 44which seats about ythe crimped marginal edge of the housing 4 I4, and alip 45 is removably supported on a pin or pins 46 mounted on the rearwall 36 of the housing I4. A plate "41 covers the converter opening 20and is removably secured to the cleaner body by means of spring clips43, 43 one of which ,engages a flange 43 on the larcuate wall I9 and theother projects through an opening in the front walls I6 'and 33.

A pair of metal stampings 50 and 5I cooperate to'form the fan casingsection I2 and an exhaust passageway 52; The stamping 50 includes afront wall 53 provided with a fan eye 54`and a peripheral wall 56 whichterminates in a marginal iiange 5'I, and a part 58 of the peripheral'52. When the'fan casing section I2 is completedv it is inserted in theopening 25 in the base I3 until it rests upony the edges of the vopening 25 and thereafter it is spot welded to the base I3 and totherear wall 36 of the housing I4. Inorder to complete the fan casing andprovide a fan chamber 60, a stamped metal wall 6I is removably attachedby nut and bolt connections to the marginal flange 51 of the fan casingsection I2.

A bearing 63 is mounted in the fan casing wall 6I to support one endof'an armature shaft 64 of a motor enclosed in a housing which has abearing 66 to support the other end of the armature shaft and thehousing 65 is removably mounted on the fan casing wall 6I by screws y68. Supported on the armature shaft 64 is a fan 'I0 disposed in the fanchamber 60 and at the extreme forward end of the armature shaft is apulley 'II disposed in the suction passageway 39. A belt 'I2 extendsfrom the pulley II` to a brush 13 rotatablymounted'in the end'walls 35,35

of the housing u to rotate the brush into `contact with the surfacebeing cleaned.

Mounted on the depressed wall 22 rearwardly of the motor housing 65 is ahandl'e bracket ,15

.which pivotally supports the handle 16. Formed casing which projectabove the base I3 are en-` 'closed by the stamped steel shell `II whichhas a cut-o section 83 to span the exhaust passageway 52 and has itsmarginal edge resting on the apron 2i and the top wall I8 of the baseI3. The forward end 85 of the shell II is spaced from the arcuate wallI3 of the base I3 to provide an opening 8B for the escape of light raysfrom an electric lamp 81 mounted in a bracket 33 supported on the shellIl. The shell is removably mounted on the base I3 by means of pins 33 onthe handle bracket 'I5 and which extend through openings in the rea'r.wall 30 of the shell II while the front end of the shell is secured tothe basei3 by means of` unshown screws. A furniture guard 93 isremovably mounted on the upper front wall of the shell I I.

In assembling the parts, the housing I4 is inserted in the nozzlesection I5 of the base I3 and spot welded thereto and the marginal edge4|) crimped over the marginal edge 4I of the nozzle section I 5. The fancasing section I2 is then placed in the opening in the'base I3 and spotwelded to the latter and to the rear wall 36 of the housing Il.Thereafter the motor and the fan casing wall 6I are placed as a unit inthe recess 25 and moved forwardly to place the motor pulley 'II and fan10 in-their proper positions and the fan casing wall 6I is then boltedto the marginal edge 51 of the fan casing section I2. The handle 'I6 ispivotally mounted on the bracket 15, and the ,shell I I is attached byplacing the end wall 90 over the pins 39 and thenv the forward end ofthe shell is moved downwardly into contact with the base I3 to which itis rigidly secured by unshown screws.
